Summary:This memoir (price up to 35.00), rather than covering one specific 1:50 000 scale map, focuses on a stratigraphical unit covering several of these map sheets. The spectacular scenery (much of the area having been designated a National Park) arises from glacial erosion and the underlying Lower Palaeozoic rocks The Skiddaw group consists of Tremadoc to LLanvirn, deep-water, marine turbidite mudstones and sandstones, whose cleaved mud-rich lithologies weather to form the rounded topography that typifies the north of the Lake District. The highest and most rugged parts of the group, at Skiddaw, Blencathra and Grasmoor, have been hornfelsed by igneous intrusions. In this memoir, there are chapters on the biostratigraphy (graptolites and microfossils), lithostratigraphy, depositional environment, structure, metamorphism and regional correlation. In appendices, compositional data, with geochemical and modal analyses, are given for the Skiddaw group,along with means and range of petrographic data for many of the formations. [R.A.H.]
